Such of the believers as stay (at home) excepting the disabled ones, and those who strive in the cause of Allâh with their substance and their lives, are not equal. Allâh has exalted in rank those who strive (in His cause) with their substance and their lives above those who stay (at home), and yet to each one Allâh has promised good but Allâh has indeed granted eminence to those who strive (in His cause) over those who stay (at home) by giving them much better reward.
